Definitions

  • the invention relates generally to tires for bicycles and vehicles.
  • Tire treads provide grip by generating friction with the ground surface. Too little friction may enable ease of riding with less resistance, such as with a road bicycle, but provide insufficient traction for certain terrains and road conditions. Therefore, a need exists to improve tire friction.
  • a tire comprises a first knob and a second knob.
  • the first knob has a first knob length and first knob width. At least one of the first knob length and first knob width is less than 2mm.
  • the second knob has a second knob length and a second knob width. At least one of the second knob length and second knob width is less than 2mm.
  • the first and second knobs are positioned no more than a distance of 2mm from each other.
  • the first knob and second knob may be preferably disposed in a recess including a recess base and a recess sidewall with a top ledge.
  • the recess defines a depth extending from the base to the ledge.
  • the first knob has a first top surface that may protrude beyond the ledge, be substantially flush with the ledge, or lie beneath the ledge.

  • a tire comprises a tire circumference, a first knob and a second knob, wherein the first and second knobs are preferably positioned no more than a distance 0.12% of the tire circumference from each other.
  • the first knob has a first knob length and a first knob width. At least one of the first knob length and the first knob width is preferably less than 0.15% of the tire circumference.
  • the second knob has a second knob length and a second knob length. At least one of the second knob length and the second knob width is preferably less than 0.15% of the tire circumference,
  • the first knob and second knob are preferably disposed in a recess comprising a base and a recess wall with a ledge.
  • the recess defines a depth extending from the base to the ledge.
  • The may further comprise a groove in fluid communication with the recess that is configured to capture and direct liquid away from the recess.
  • the first knob may be attached to, or separate from, the second knob.
  • At least one of the first knob length and first knob width is preferably less than 2mm. At least one of the second knob length and second knob width is preferably less than 2mm.
  • the tire further comprises a tire width. At least one of the first knob length and first knob width is preferably less than 5% of the tire width. At least one of the first knob length and first knob width is preferably less than 5% of the tire width.
  • a tire comprises an outer circumference, a tire width, a first knob and a second knob.
  • the first knob has a first length less than 2.5mm and a first width less than 2.5mm.
  • the second knob has a second length less than 2.5mm and a second width less than 2.5mm.
  • Each knob preferably has a height greater than 0.4mm.
  • the first and second knobs are positioned no more than a distance 0.12% of the tire circumference from each other.
  • the first knob and second knob are preferably disposed in a recess including a recess base and a recess wall with a ledge.
  • the recess defines a depth extending from the base to a circumferential surface of an adjacent tire portion.
  • the tire may further comprise a groove in fluid communication with the recess that is configured to capture and direct liquid away from the recess.
  • a first preferred embodiment of a tire is illustrated in Figure 1 and designated generally by the reference numeral 10.
  • the tire 10 may be configured for use with bicycles, scooters, motorcycles, automobiles, trucks, tractors and any other ground vehicle or toy requiring tires.
  • the tire 10 comprises an outer circumferential surface, or simply outer surface, 20 that is configured to touch the ground surface.
  • the total surface area of the outer surface 20 defines a "ridable" surface area, which may also be considered the product of the outer circumferential surface times the tire width.
  • the outer surface 20 defines a tire circumference 22.
  • a pair of sidewalls 24 extend radially inward from the outer surface 20.
  • the tire 10 also defines a tire width 26 between the sidewalls 24, as shown in Figure 1 , and a circumference 22 and diameter 28, as shown in Figure 3 .
  • the tire 10 comprises tire knobs, or simply knobs, 30 extending radially outward from the outer surface 20 in circumference.
  • the tire 10 preferably comprises knob groups 32 where each group 32 includes a plurality of closely positioned knobs 30.
  • the size of each tire knob 30 is substantially small relative to the size of the tire. Additionally, the distance of spacing between adjacent knobs 30 is preferably small relative to the size of the tire.
  • FIGS 1-3 show a preferred tire 10 for use in connection with bicycles.
  • the preferred knobs 10 resemble bristles due to their substantially small lengths and widths relative to the size of the tire 10.
  • the knobs 30 also resemble bristles in that a plurality of knobs 30 are closely positioned together and being separated, if at all, by a substantially small distance of spacing between adjacent knobs 30.
  • the specific dimensions of the knobs 30 and their arrangement and placement significantly manage the effects of hysteresis.
  • each knob group 32 may be disposed, or contained, within an optional tire recess 34 that lowers or indents the tops of the knobs 30 radially inward relative to the tire outer surface 20 along the major diameter. Therefore, the knobs 30 extend to a height less than they would without the recess 34.
  • a plurality of knobs 30 substantially fill out the enclosed recess 34, leaving a minor gap 43 between the recess wall, or boundary, 41 and adjacent knobs 30 on the perimeter of the group 32.
  • each recess 34 comprises a space indented into the tire outer surface 20 and bordered by a boundary, or recess perimeter 36, that preferably forms a closed loop.
  • the recesses 34 collectively define a minority of the surface area of the ridable surface area such that the surrounding raised tire portions collectively define a majority of the ridable surface area.
  • the recess 34 acts as a threshold limiting the knobs' 30 exposure to the ground surface. Without the recess, the knobs 30 would be fully exposed to the ground surface and easily subjected to wear and/or breakage in certain placements due to the size of the knobs.
  • the recess "protects" knobs 30 therein and artificially limits their exposure to the surface.
  • Effects of hysteresis may be better managed by altering the level of the knobs' 30 surface exposure by differing sizes of recess (area and/or depth) matched to differing sizes/arrangements of knobs 30 (below, above, or even with walls of recess).
  • employing recesses 34 disposes the knobs 30 radially inwardly with respect to the raised majority tire portions, thereby reducing resistance when rolling without compromising traction. Resistance is reduced by not having the full height of the knobs 30 protrude beyond the circumferential outer surface 20 of the tire which would otherwise enable greater deformity of the knobs when compressed against the ground.
  • Each knob 30 defines a length 37 and width 38. Each knob also defines a height 39, which can be varied as shown in Figures 9-12 . While it may be desirable to form all knobs 30 on a single tire 10 with uniform dimensions, it is contemplated that a tire 10 may include knobs of differing lengths, widths and heights, even within a knob group 32. As examples and not by way of limitations, the length 37 and/or width 38 of each knob may be less than 10% of the tire width "W", and more preferably less than 5% of the tire width 26.
  • each knob 30 would have a length or width less than 5mm, and more preferably, less than 2.5mm.
  • the tire width 26g may be 220mm, for example, in which case each knob 30 would have a length or width less than 22mm, and more preferably, less than 11mm.
  • the tire width 26g may be 700mm, for example, in which case each knob 30 would have a length or width less than 70mm, and more preferably, less than 35mm.
  • the length 37 and/or width 38 of the knob 30 may also be less than 1% of the tire circumference "C,” and more preferably less than 0.15% of the tire circumference.
  • the size of the knobs are very small in relation to the size of the tire as defined in proportion to the tire's width and/or circumference.
  • the length 37 and width 38 of the knob 30 are each preferably less than 2mm, and the height is at least 0.4mm. In a preferred embodiment, the length, width and spacing between knobs may be 2mm or less even where the tire 10 is configured for use with anything other than a bicycle (e.g., vehicles).
  • each knob 30 may be attached or detached from adjacent knobs 30. Where adjacent knobs 30 are detached, the spacing between adjacent knobs are preferably no more than 10% of the tire width W, and more preferably no more than 4% of the tire width W. Alternatively, the spacing between adjacent knobs may be no more than 1% of the tire circumference 22, and preferably no more than 0.12% of the tire circumference 22. Where the tire 10 is adapted for use with bicycles, the spacing between adjacent detached knobs 30 are preferably no more than a distance of 2mm.
  • the knobs 30 may be attached to, or detached from, each other. As shown in Figure 1 , transverse rows of attached knobs and detached knobs may be arranged in an alternating pattern to form a matrix that comprises the group 32. When detached, a knob 30 comprises an individual member separate from adjacent knobs 30. When attached as shown in the first preferred embodiment in Figure 1 , an array or matrix of attached knobs 30 may be formed in any desired geometric line or shape. In Figure 1 , the knob group 32 comprises, for example, three rows of detached knobs and three rows of attached knobs 30, each row forming a straight line extending across the tire width 26. It is contemplated that attached knobs 32 may be formed into curved lines and a variety of other lines and shapes.
  • each knob 30 is preferably distinguishable from other joined knobs 30 in that each knob 30 forms a distinct shape and structure (e.g. circular, square, triangular, etc.) that is preferably repeated with all the knobs 30 in the attached array.
  • a distinct shape and structure e.g. circular, square, triangular, etc.
  • Figure 2 is a top plan view of the first preferred embodiment.
  • a slight gap 43 is disposed between the recess wall 41, or border, and the adjacent knobs 32.
  • a pair of grooves 50 are in fluid communication with each recess 34 and configured to direct any fluids away from the recess and ultimately away from the tire 10. Grooves 50 helps to channel fluid away from knobs 30 to enhance tread-to-surface/terrain contact when the tire rolling over wet surface/terrain.
  • knob groups 32 may be formed with variations in spacing between knobs, spacing between knobs and recess walls, knob heights, attached versus detached knobs, and shapes and dimensions of recesses.
  • FIG. 4 shows a second preferred embodiment of a tire 10b where elements of similar structure are designated by the same reference numerals followed by the lower case "b."
  • a knob group 32b comprises a combination of detached, individual knobs 30b-1 having a first shape and attached knobs 30b-2 having a different, second shape.
  • the detached individual knobs 30b-1 are closely spaced to adjacent knobs in the preferred range of distances discussed above and may be arranged in rows or any other desired configuration.
  • preferably no gap is formed between the recess walls 41b and adjacent knobs 30b-1, 30b-2.
  • the recess 34b comprise an asymmetrical, elongate shape.
  • a tire 10c does not comprise any recesses.
  • the tire 10c may simply comprise groups 32c of closely positioned knobs 30c, shown detached in this embodiment.
  • a tire 10d comprises at least one knob group 32d including both attached knobs 30d-1 and detached knobs 30d-2 in a random pattern.
  • the knobs 30d-1, 30d-2 may be formed into a limitless variety of shapes, e.g., triangular knobs as shown in Figure 6 .
  • the recess 34d may also be formed into a limitless variety of shapes and dimensions.
  • the knobs 30 in the illustrated embodiment in Figure 6 the recess 34d has a generally triangular shape.
  • a tire 10e may comprise a configuration of knobs 30e within a group 32e so as to form letters, numbers, symbols, graphics and/or images.
  • Each group 32e contained within a corresponding recess 34e may repeat the same marking or show different markings. Therefore, a way to market and brand product is provided according to the invention. For example, a company can employ configurations of recess and knob groups to identify their brand on the tire.
  • a tire 10f comprises groups 32f of knobs 30f disposed in corresponding recesses 34f, each forming an image or graphic, which in this illustrated embodiment comprises a tree or arrowhead, for example.
  • the grooves 50f in fluid communication with each recess 34f can assist in forming the graphic design or artwork.
  • Figures 9-12 illustrate varying the heights of knobs contained within a tire recess and/or varying the depth of the recess in order to create the desired position of the tops of the knobs in relation to the outer circumferential surface 20 of the tire 10.
  • Figures 8-11 each illustrate a recess 34 having a recess base 52 and a recess wall 41, with the distance between the base 52 and the ledge 54 of the recess wall 41 defining a depth 56 of the recess 34.
  • the knob height is 0.4mm or greater. Such a preferred height allows each knob to deflect and/or deform to add sufficient friction or affect hysteresis in a meaningful way.
  • each knob 30 has a knob height 39 greater than the recess depth 56 such that the knob top 60 protrudes a distance 62 radially outwardly beyond the ledge 54.
  • the knob height 39 is substantially equivalent to the recess depth 56 such that the knob tops 60 are substantially flush with the ledge 56.
  • the knob height 39 is less than the knob depth 56 such that the knob tops 60 lie beneath the ledge 56. It will be appreciated that the shorter configuration of knobs in Figure 11 will generate less resistance than the flush configuration of Figure 10 which generates less resistance than the protruding configuration of Figure 9 .
  • Figure 12 illustrates a knob group 32 disposed within a recess 34 having knobs 30-1, 30-2 and 30-3 of varying heights.
  • a first knob 30-1 has a shortest height 39-1 such that its knob top 60-1 lies beneath the ledge 54.
  • a second knob 30-2 has a middle height 39-2 such its knob top 60-2 is substantially flush with the ledge 54.
  • a third knob 30-3 has the greatest height 39-3 such its knob top 60-3 protrudes beyond the ledge 54.
  • FIG 13 illustrates a preferred embodiment of a tire 10g configured for use with automobiles, where elements of similar structure are designated by the same reference numerals followed by the lower case "g."
  • the tire 10g has a tire width 26g that is substantially wider than the bicycle tire shown in Figures 1-3 .
  • This car tire 10g preferably omits recesses and comprises groups 32g of knobs 30g.
  • Each knob 30g has a length or width that is preferably less than 10% of the tire width 26g, and even more preferably less than 5% of the tire width 26g.
  • the length 37g and/or width 38g of the knob 30g is also preferably less than 1% of the tire circumference, and more preferably less than 0.15% of the tire circumference.
  • FIG 14 illustrates a preferred embodiment of a very large tire 10h configured for use with tractors, trucks, heavy duty vehicle, where elements of similar structure are designated by the same reference numerals followed by the lower case "h.”
  • the tire 10h has a tire width 26h that is even wider than the car tire shown in Figure 12 .
  • This giant tire 10h preferably omits recesses and comprises groups 32h of knobs 30h, which may be formed adjacent to grooves 70 and other forms of tire tread.
  • Each knob 30h has a length or width that is preferably less than 10% of the tire width 26h, and even more preferably less than 5% of the tire width 26h.
  • the length 37h and/or width 38h of the knob 30h is also preferably less than 1% of the tire circumference, and more preferably less than 0.15% of the tire circumference.
